China's National Cancer Center has released a comprehensive new report tracking shifts in the country's malignant tumor trends over the past two decades, with ETtoday新聞雲 reporting that newly diagnosed thyroid cancer cases have climbed to third place nationwide. The demographic shift highlights a widespread increase in detection rates among young adults, even as traditional upper gastrointestinal cancers decline.
National Cancer Center Estimates millions of New Cases in 2024
The National Cancer Center released its analysis titled Age Characteristics of Cancer Incidence and Mortality in China, 2024, estimating roughly 5.15 million new cancer diagnoses and 2.58 million deaths across the country for the year. According to data cited by Sing Tao Daily, the report reveals a historic structural transformation in the nation’s disease mapping when compared to figures from the mid-2000s.
Two decades ago, the top five most common cancers were dominated by digestive tract malignancies, consisting of lung, stomach, liver, esophageal, and colorectal cancers. In the 2024 projections, lung cancer, female breast cancer, thyroid cancer, colorectal cancer, and liver cancer make up the top five. Stomach cancer and esophageal cancer have dropped out of the leading group entirely, while thyroid cancer surged upward from outside the top tier.
Thyroid Cancer Ranks First Among Young Adults
Thyroid cancer’s ascent to the third most common newly diagnosed cancer represents the most dramatic statistical shift in the report. According to findings covered by Sing Tao Headline, thyroid cancer now ranks as the most frequently diagnosed malignancy among both men and women aged 20 to 39, and holds the top spot among women aged 20 to 59.
Oncological experts consulted by the reporting outlets explain that this surge does not indicate a parallel rise in lethal risk. Instead, the dramatic increase stems largely from the widespread clinical and routine use of neck ultrasound and computed tomography examinations during health checkups, which has led to significant over-diagnosis of early-stage, slow-growing tumors. Despite the high number of new cases, thyroid cancer maintains a high five-year survival rate.
Mortality Rankings and the Burden of Aging
While diagnostic patterns change, the country’s leading causes of cancer death remain severe, with lung cancer maintaining its position at the top for both incidence and mortality. Colorectal cancer has climbed to third in overall cancer mortality—surpassing both stomach and esophageal cancers—a trend experts attribute to rising red meat consumption, obesity, and sedentary lifestyles. In female mortality statistics, colorectal cancer now ranks second.
Infectious disease prevention efforts have successfully reduced upper digestive tract cancer rates, driven by hepatitis B vaccination programs and the treatment of Helicobacter pylori infections. However, population aging continues to intensify the overall healthcare burden, with individuals aged 60 and older accounting for 61.77% of all new cancer diagnoses and 79.02% of all cancer-related deaths.
Why Thyroid Cancer Rankings and Risk Groups Changed?
Why did thyroid cancer jump in the rankings if it is not becoming more lethal?
Oncological experts note that the surge is primarily driven by the widespread adoption of high-resolution neck ultrasound and CT scans in routine physical examinations. This increased screening detects many small, indolent tumors that previously went unnoticed, leading to a high rate of detection without a corresponding spike in mortality risk.
Which age groups face the highest risk for thyroid cancer according to the data?
Data from the National Cancer Center shows that thyroid cancer is the most frequently diagnosed malignancy among both men and women in the 20 to 39 age cohort. It also ranks as the number one newly diagnosed cancer among women aged 20 to 59.
What factors are driving the rise in colorectal cancer mortality?
Analysts point to modern lifestyle factors such as increased red meat intake, rising rates of obesity, and sedentary daily habits as primary contributors. These behavioral shifts have pushed colorectal cancer deaths above stomach and esophageal cancers to rank third overall, and second among women.
